Patent DE-19501993-A1 (DE)
Inventor: MATERNE HORST DR ING
IPC: B61L23/22
Filed: 1995-01-11
Abstract: With prior art systems, the safety of railway travel is ensured largely by means of fixed signals which visually signal to the train driver an interdiction or authorization to proceed. For high speeds, complementary systems providing driver's cab signalling and acting linerarly on the train have come into use. Owing to their high safety requirements, however, such systems involve very high capital and operating costs. In the method proposed, when authorization to proceed is required the status of each of the track-safety installations relevant to a particular length of track is determined by interrogating the installations in accordance with a predetermined programme by radio, using a device fitted on board the traction unit, and the status of each safety installation is compared with reference data stored in the system for this length of track to determine conformity with pre-defined criteria. If these criteria are met, authorization is given to proceed along the length of track, the authorization being indicated visually on the display in the traction unit in addition to the track display. The method proposed can be used for the collection, processing and visualization of status data for the control of safety-relevant processes. It is particularly suitable for the economical operation of tracks with light or medium-intensity traffic. If the device in the traction unit is a mobile one, there are no restrictions on the operation of other traction units.
Patent DE-19506192-A1 (DE)
Title: Absorption spectrometer for identifying precious stone
Inventor: GASSNER CHRISTIAN
IPC: G01N21/3563
Filed: 1995-02-23
Abstract: The spectrometer includes a continuous spectrum light source (1) which supplies a bifurcated fibre-optic probe (3) with light for illuminating the stone (6) under examination. The returned light travels back through the probe to enter a variable monochrome diffraction stage (8-13).  In the diffraction stage a grating (11) is mechanically rotated to permit light of gradually increasing wavelength to be registered by an opto-electronic sensor (14). In this way a complete spectrum analysis (16) is progressively obtained for processing (15) and comparison with known standards.

Title: Cavitation bubble and ultrasound field strength measurement method in fluids
Inventor: NIEDERDRAENK TORSTEN DIPL ING
IPC: B01J19/10
Filed: 1995-12-11
Abstract: The measurement method introduces, to the primary excitation by an ultrasonic field of high intensity needed for the production of the cavitation fields, a secondary HF ultrasonic field. The amplitude of the sound parts forming by intermodulation effects are extracted, for deciding the bubble density and the cavitation intensity in the cavitation field. The secondary excitation results by continuously introduced single frequency signals or a single wave train, of such a monofrequency signal. The frequencies of the secondary excitation signals are varied with successive measurements for the determination.

Patent DE-19610164-A1 (DE)
Title: Interleaver matrix synchronisation method
Inventor: BRAUNAGEL FRANZ
IPC: H03M13/27
Filed: 1996-03-15
Abstract: The method involved is using the highest valued bit of the counter for the change from the input to the read-out matrix. As long as the page zero is not full, the highest valued bit is still zero, and this means that the data has been entered on the page zero. The inverter inverts the highest valued bit, indicating that 1 has been read from page 1. If page zero is full, the highest valued address bit increases by 1, and this means that 1 has been entered into page 1 and read from the page zero.

Title: Flow-type heater for instant heating of service water
Inventor: SCHWARZ HANS-JOCHEN DR
IPC: F23N1/08
Filed: 1996-06-15
Abstract: The heater (1) has a heat transformer (2) arranged close to a burner (3). The burner is provided with a gas/water controller (7) and two gas valves (9,22). The first valve (9) controls the supply gas flow throttle and the second valve (22) controls the inflow throttle of the gas flow.

The second valve is actuated through an electric actuator (24), its operation depending on the comparison of the outlet (28) water temperature and a set value. When the second valve is in a steady position, the gas flowing through the first valve is proportional to the water flow through the heater; when the second valve is in a steady position the gas flow through the first pipe is proportional to the signal of a control device (42).

Title: Vibrating ram for piles in building construction
Inventor: HEICHEL CHRISTIAN
IPC: E02D7/18
Filed: 1996-08-08
Abstract: The ram has a driving head (1) which grips the piles, or posts, and drives them into the ground. A control unit (9) is linked to sensors (10) on the driving head and controls the amplitude of the vibrations. The vibrator drive is kept above a set lower threshold frequency related to the resonant frequency of the ground (6). This prevents damage to adjoining structures. The threshold frequency is set a little above the resonant frequency of the ground. The applied amplitude is related to the operating frequency above the threshold value. The rate at which the pile/post is driven into the ground is monitored by other sensors and is controlled by the control unit. The same ram system can be used to pull posts out of the ground.
